#1 seeds are kinda legal b/c they don't have THC. plus they don't really smell that bad, so if you vacuum seal the bag and hide it in the back of a cd case or something then it gets right through customs. weed does too for that matter....

#2 get a 20 oz. plastic soda bottle. poke a hole in it about the size of a regular bic pen. take both ends off of the pen. cut a square off of an aluminum can and roll it into a cone and stick it into the pen. stick the pen through the hole in the bottle and put some gum around the pen to seal up the hole in the bottle. put some water into the bottle and put the weed into the aluminum bowl. then smoke it yo. that sounds complex as hell i'm sure but i'm stoned.

#3 yes but glass pipes taste better
